Question

I binded a property with resource typed array and it works fine in the inspector like below.

However, when I launch the game, the value in the second item is wrong and behaves like an undefined value.
The KeyBinding class is below.

class KeyBinding : public godot::Resource {
    GDCPP_REQUIRE_BINDING(KeyBinding, godot::Resource);

    GDCPP_PROPERTY("LeftStick,RightStick,LeftStickButton,RightStickButton,Up,Down,Left,Right,A,B,X,Y,LB,RB,LT,RT,Start,Select", PROPERTY_HINT_ENUM, key, get_key, set_key, INT, PROPERTY_USAGE_DEFAULT)
    GDCPP_PROPERTY("Pressed,Just Pressed,Just Released", PROPERTY_HINT_ENUM, operation, get_operation, set_operation, INT, PROPERTY_USAGE_DEFAULT)
    GDCPP_PROPERTY("", PROPERTY_HINT_NONE, state_id, get_state_id, set_state_id, INT, PROPERTY_USAGE_DEFAULT)
    GDCPP_PROPERTY("", PROPERTY_HINT_NONE, queue_action, is_queue_action, set_queue_action, BOOL, PROPERTY_USAGE_DEFAULT)
public:
    GDCPP_METHOD(get_key)
    BindingKeyTypes key() const { return _key; }

    GDCPP_METHOD(set_key)
    void setKey(BindingKeyTypes key) { _key = key; }

    GDCPP_METHOD(get_operation)
    BindingOperations operation() const { return _operation; }

    GDCPP_METHOD(set_operation)
    void setOperation(BindingOperations operation) { _operation = operation; }

    GDCPP_METHOD(get_state_id)
    s32 stateId() const { return _stateId; }

    GDCPP_METHOD(set_state_id)
    void setStateId(s32 stateId) { _stateId = stateId; }

    GDCPP_METHOD(is_queue_action)
    bool isQueueAction() const { return _queueAction; }

    GDCPP_METHOD(set_queue_action)
    void setQueueAction(bool queueAction) { _queueAction = queueAction; }

private:
    BindingKeyTypes _key = BindingKey_LeftStick;
    BindingOperations _operation = BindingOperation_Pressed;
    s32 _stateId = -1;
    bool _queueAction = false;
};

VARIANT_ENUM_CAST(gameplay::BindingKeyTypes);
VARIANT_ENUM_CAST(gameplay::BindingOperations);

The bind method is below.

	void KeyBinding::_bind_methods() {
		ClassDB::bind_method(D_METHOD("get_key"), &KeyBinding::key);
		ClassDB::bind_method(D_METHOD("set_key", "key"), &KeyBinding::setKey);
		ClassDB::bind_method(D_METHOD("get_operation"), &KeyBinding::operation);
		ClassDB::bind_method(D_METHOD("set_operation", "operation"), &KeyBinding::setOperation);
		ClassDB::bind_method(D_METHOD("get_state_id"), &KeyBinding::stateId);
		ClassDB::bind_method(D_METHOD("set_state_id", "stateId"), &KeyBinding::setStateId);
		ClassDB::bind_method(D_METHOD("is_queue_action"), &KeyBinding::isQueueAction);
		ClassDB::bind_method(D_METHOD("set_queue_action", "queueAction"), &KeyBinding::setQueueAction);
		ClassDB::add_property(get_class_static(), PropertyInfo(Variant::INT, "key", PROPERTY_HINT_ENUM, "LeftStick,RightStick,LeftStickButton,RightStickButton,Up,Down,Left,Right,A,B,X,Y,LB,RB,LT,RT,Start,Select", PROPERTY_USAGE_DEFAULT), "set_key", "get_key");
		ClassDB::add_property(get_class_static(), PropertyInfo(Variant::INT, "operation", PROPERTY_HINT_ENUM, "Pressed,Just Pressed,Just Released", PROPERTY_USAGE_DEFAULT), "set_operation", "get_operation");
		ClassDB::add_property(get_class_static(), PropertyInfo(Variant::INT, "state_id", PROPERTY_HINT_NONE, "", PROPERTY_USAGE_DEFAULT), "set_state_id", "get_state_id");
		ClassDB::add_property(get_class_static(), PropertyInfo(Variant::BOOL, "queue_action", PROPERTY_HINT_NONE, "", PROPERTY_USAGE_DEFAULT), "set_queue_action", "is_queue_action");
	}

The debugging info is below.

The info shown in the picture is the second item in my resource array.
I don’t know why the enum value is like an undefined value, but I am sure that I modify it correctly in the inspector.
Any suggestion will be appreciated. Thanks.

Sorry, I forgot to put the enum definitions, I put them below.

enum BindingKeyTypes {
    BindingKey_LeftStick,
    BindingKey_RightStick,
    BindingKey_LeftStickButton,
    BindingKey_RightStickButton,
    BindingKey_Up,
    BindingKey_Down,
    BindingKey_Left,
    BindingKey_Right,
    BindingKey_A,
    BindingKey_B,
    BindingKey_X,
    BindingKey_Y,
    BindingKey_LB,
    BindingKey_RB,
    BindingKey_LT,
    BindingKey_RT,
    BindingKey_Start,
    BindingKey_Select,
};

enum BindingOperations {
    BindingOperation_Pressed,
    BindingOperation_Just_Pressed,
    BindingOperation_Just_Released,
};

Note: It sometimes behaves correct, but after a bunch of relaunch of my editor, it suddenly occurs.
